Here's a list of weapon changes in the 27th October patch for BF4.Site database hasn't been updated yet.

This patch was mainly about vehicles. However putting that data on site in tidy format is much harder than weapons.
If you want to dig into what all changed you can see the "full changelog"/file difference from Symthic's databrowser.

So feasible if people were to actually check what was out of date and request corrections? Gee if only we had an entire community of number-crunchers and statistic-nerds that could do that
But I'm derailing, I'll try and keep an eye out

So they nerfed the long range option of Flechette as well? And no,Slugs are useless because of the defense perk.There is literally no reason to run flechette except to shoot through objects.It already does crap all damage, and that is frankly a death sentence to a pump.
